#1 Aftermarket Cylinder in the World!
With well over 100,000 currently in service around the world and millions of flight hours behind them, Superior’s Millennium Cylinders® are without question, the most popular FAA-approved, PMA aftermarket cylinders in all of general aviation.
But Superior is not just the world’s #1 dedicated cylinder supplier we are also the leader in cylinder design and performance innovation.
Each Millennium Cylinder is an engineering and manufacturing masterpiece. From its advanced computer generated head fin configuration, to its 3-D port contour and increased wall thickness, to its advanced aluminum alloy heads and through hardened AMS 6382 steel barrel, Millennium Cylinder’s deliver performance and quality benefits far surpassing anything else in the air.
Looks great. Performs better.
Put any Millennium Cylinder side-by-side with any other OEM or aftermarket cylinder and the difference in quality, craftsmanship and attention to detail is strikingly obvious.
And while it looks really great, it performs even better. Millennium Cylinders resist cracking, run cooler, last longer and generally out perform the standard cylinders available from Lycoming, Continental or any other aftermarket supplier.
We’re so confident in the Millennium Cylinder’s performance that it’s covered by a full 25-month/TBO* (whichever comes first) warranty. It’s one of the best in the business.

SUPERIOR MILLENNIUM CYLINDER SL36006W-A20P COMPLETE
Great Product, good price , fast shipping
Great quality but I wish they would go ahead and size the rings and install the piston, like they used to do. Would also be nice to be able to request a specific piston weight to better match what was removed from the engine or the opposite cylinder piston. I ended up using my old piston in the new cylinder to avoid a 20+ gram mismatch.
